Hi Jürgen!
I like very much the "treemap" !
Does the surface could vary depending of a "weight'? in my projects, I
collect "usage data"
(how many times a concept is used in a given index or application).
The surface of each concept could be linked to this weight ?
(I do not see any in
http://turnguard.com/opendirectory/prefuse/OpenDirectoryTreeML.xml )
May be you know the display of WinDirStat, a very handy program to
manage your hard disk:
http://windirstat.info/
It is a lot similar (in its principle) to your treemap.
Good evening!
Christophe
